APPARATUS FOR FILLING SAND-BOXES OF LOCOMOTIVES.

SPECIFICATION forming part of Letters Patent No. 767,679, dated August16, 1904.

I Application filed March 14, 1904. Serial No. 198,170. (No model.) v

, Boxes of Locomotives; and I do hereby declare the following to be afull, clear, and exact description, such as will enable others skilledin the art to which it appertains to make and use the same. I

My invention relates to improvements in methods of filling thesand-boxes of locomotives.

, Heretofore the practice has been to fill the sand-box of a locomotiveby means of buckets handled by the employees of the road, it requiringseveral men to accomplish the result, which has been veryunsatisfactory, owing to the time expended, the waste of sand upon thelocomotive, and consequent injury to the machinery of the same.

In order to understand the working of my invention more fully, referenceis had to the accompanying drawings, in which- Figure 1 represents aside view of a locomotive standing upon the track beside my apparatuswith a partial sectional view of the same and the sand-box of theengine. Fig. 2 is a plan view of the same. Fig. 3 is a detailed view ofa part of the filling apparatus. Fig. 4 is a detailed sectional view ofthe sandbox with a part of my apparatus.

My device consists of a reservoir A to hold a sufficient supply of sand,a curved and swiveled pipe G to convey the sand to the sand-box B fromthe reservoir, a force-pipe D entering the pipe C at the bottom of thesame and connected with a stand-pipe F, situated near the rear end ofthe tender of the locomotive. This stand-pipe F is provided with a shortflexible pipe (3, with a coupling upon the end of it, which coupling ismade to conform with the coupling upon the train air-pipes.

sand.

' In operation the air-pipe Gr at the rear of the tender is uncoupledfrom the foremost car and coupled to the pipe C of the stand-pipe. Theair-pressure is then turned on from the locomotive and rushing throughthe pipe D creates, such a currentthrough the pipe C that the sand isdrawn through apertures E in the lower part of the pipe C and carriedinto the sand-box. At the end of the pipe C at the sand-box is aflexible bell-mouthed pipe d,

which enters the sand-box and delivers the It is made in this shape sothat the pressure of the air-current is distributed and its forceweakened at that point.

As is seen in Fig. 2, the pipe C (shown also by dotted lines) is swungout of the way when not in use.

The pipe 0 rests upon a block a and passes through a cross-bar b,stretching across the reservoir-framework.

Various methods may be used in constructing the reservoir and pipes onthe same general plan without altering the principle of this device.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is 1. The combination with the sand-box of alocomotive, a pipe D, connecting with the airpipe of the locomotive, asupply-pipe C. entering or being connected with the sand-box of thelocomotive and a reservoir A supplying sand, the whole being operated bythe force of the air from the locomotive substantially as shown.

2. The combination of the flared pipe (Z,

supply-pipe C, reservoir A, pipe D, stand-pipe F with air-brakecoupling, arranged substantlally as herein described.
